Boundary value problems

Is there a Mathematica package/routine to solve O.D.E's, numerically,
in a boundary value problem?

(i.e. conditions of the form :

                y[x1] == a1
                y'[x2] == a2
                ...

                where x1 != x2)

I've tried NDSolve but get an error message :

    NDSolve::ndinn: Initial condition y[-1000.] is not a number.
